Doing light, steady exercise like walking or slow cycling doesn’t seem to change blood sugar levels much in healthy adults who don’t usually exercise.

Lifting weights can help your body handle sugar better, making your blood sugar levels more stable after meals.

Some endurance athletes can have blood sugar levels that look like they're prediabetic or diabetic, even though they're actually healthy, because their bodies use up glucose so fast during training.

Lifting weights might help older people with type 2 diabetes lower their blood sugar a little bit in the short term.

Doing really intense endurance workouts might raise your blood sugar levels and make it look like you have diabetes, even if your body is actually super healthy.

In sedentary adults with prediabetes, a specific form of short, intense exercise performed three times per week for twelve weeks increases the body's ability to respond to insulin in muscle and fat tissue, improving glucose control.
